Auto Off Function
When the appliance is not in AUTO OFF mode and
the room temperature reaches the temperature
setting the appliance will reduce the gas
flow and maintain the flame on the lowest
flame level. The temperature may continue
to rise even on this low setting. If the
temperature reaches
104° F (40° C) then the

reached. To enter this
mode press the AUTO OFF button. The words “Auto
Off” will be displayed above the time. To exit this

When an obstruction is detected the Blockage
Indicator LED above the Receiver Window will glow
red and combustion reduces to front burner, low

To restore normal operation, remove the obstruction,
turn the appliance OFF and then ON.
